Stream cipher has always been one of the most important encryption methods in cryptography. Now we bring in a stream cipher encryption chip design which is based on neural network algorithm and it not only contains the good statistics of m-sequence but also enhances the periodicity and linear complexity of the output sequences. We use FPGA technology to complete the stream cipher circuit design and the modem electronic design method to smoothly realize operation functions and sequential assignment. The result of logical synthesis simulation verifies the correctness of the chip circuit. This research is helpful to the application of stream cipher algorithm in information security and modem secure communication equipment.
